Tool wear, caused by high machining temperatures, cutting speed or mechanical load, can have various characteristics. Current solutions for metrological quantification are limited with respect to their viewing dependency and user influence. Here, a measurement solution which is based on 3D focus variation measurements is presented. The quantification is carried out by the automatic evaluation of flank wear parameters (ISO 3685:1993, ISO 8688-1:1989) and plastic deformation impression and depression parameters on 3D dataset series. This allows the visualization and assessment of wear over a period of time and provides crucial information for the manufacturing and machining process.
